IMPROVED RUBBER CONNECTION FOR MOSQUITO-NET FRAMES. i

The Schedule referred to in these Letters Patent and making part of the same To all whom tt may concer/a:

Be it known that we, UEL W. ARMSTRONG and IRA KEENEY, of Evansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Improvement in Rubber Connections for Mosquito-Net Frames; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of thisspeciiication, in which- Figure 1 isan end vien7 of a mosquito-net frame to which our improvement has been attached, partly in section, to show the construction.

Figure 2 is a top view of the same.

Figure 3 is adetail sectional view illustrating the construction.

' Similar letters of reierenceindicate corresponding n parts.

Our invention has for its object to furnish improved means for connecting the upright and horizontal bars of a mosquito-net frame to each other, which shall be simple 'in construction and will enable the frame to be easily put up and taken down when required; and

1t consists in the construction ofthe connections as hereinafter more fully described.

-Avare three short rubber tubes at right angles with each other, and which may be formed solid in one piece, or may be securely attached to each other, as may be desired or convenient. These tubes are designed to receive the ends of the upriglit bars B and horizontal bars O D of the frame.

The tubes of the connections A may be made similar tothe part of a rubber nursing-nipple that is sprung over the mouth cfa nursing-bottle, to enable themto take a rmer hold upon the-bars B O D.

'ihe ends of the bars B (l D may be made with a circular groove around them, to enable the rubber tubes, by contracting into said grooves, to hold the said bars more securely.

.The bars B C D may be made with round tenons upon their ends of' about halt' the length of the tubes A, so that larger or smaller sets of bars may be used with the same set of rubber connections.

The central horizontal bar E is connected to the end horizontal bars O by the rubber tubes F which receive the ends ofthe said bar E, and upon the other ends of which are formed the rings b which are slipped over the end horizontal bars C, as shown` in figs. 1 and 2.

If desired, the ring tubes F 1)' may be used to form the corner or triangular connections. In this case only two tubes are used, which receive the ends of two of the bars, and which are secured to the end of the third bar by a large-headed nail or screw driven or screwed into the end of the said third bar, and the. head of which should be made so large that the rings b' ofthe tubes F cannot pass over it. i

G are short open tubes or ferrules, preferablyV of metal, which may be inserted in the rubber tubes to receive the ends of the bars of the frame, and enable larger bars to be inserted in said rubber tubes than could be without the use of said open ferrules.

Having thus described 'our invention.

XVe claim as new and desire to secure by Letters Patent- 1. 'lhe three-tube rubber connections A, for connecting the upright and horizontal bars of a mosquito'- net frame to each other, constructed substantially as herein shown and described.

'2. The ring tubes F b', whether used for connect-ing the horizontal bars or the upright and horizontal bars, substantially as herein shown and described.

3. The open tube or ferrule G, when used in combination with the rubber tubular connections A and F b', either or both, and with the bars of a mosquito-net frame, substantially as herein shown and described, and for the purpose set forth.
